Detailed Description

Base class for PSF determiners

Register all PSF determiners with the psfDeterminerRegistry using:
    psfDeterminerRegistry.register(name, class)

Parameters
----------
config : `lsst.pexConfig.Config`
    Input for configuring the algorithm
schema : `lsst.afw.table.Schema`
    Schema used for sources; passing a schema allows the
    determiner to reserve a flag field to mark stars used in
    PSF measurement, but some PSF determiners ignore this argument.

◆ init()

def lsst.meas.algorithms.psfDeterminer.BasePsfDeterminerTask.__init__	(		self,
			config,
			schema = `None`,
		**	kwds

◆ determinePsf()

def lsst.meas.algorithms.psfDeterminer.BasePsfDeterminerTask.determinePsf	(	self,
		exposure,
		psfCandidateList,
		metadata = `None`
	)

Determine a PSF model.

Parameters
----------
exposure : `lsst.afw.Exposure`
    Exposure containing the psf candidates.
psdCandidateList : `list` [`lsst.meas.algorithms.PsfCandidate`]
    A sequence of PSF candidates; typically obtained by
    detecting sources and then running them through a star
    selector.
metadata : `str`
    A place to save interesting items.

Returns
-------
psf : `lsst.afw.detection.Psf`
    The fit PSF.
cellSet : `lsst.afw.math.SpatialCellSet`
    The spatial cell set used to determine the PSF
